Hi ladyfair67,
Thank you for the donation.
If P1166 occurs with the fule injectors not getting power, most probably you have a blown fuse.
Check the following fuse.
1. POWER SEAT ( 20A) in underhood fuse/relay box.
2. # 4 ECU (ECM/PCM) CRUISE CONTROL (15A) fuse in driver's underdash fuse/relay box.
3. #6 LAF HEATER (20A) in passanger's underdashfuse/relay box.
If any of the fuses are blown check for shorting between A/F sensor relay and fuses.
ONLY use the designated fuse as replacement and testing.
